The mechanism that makes this possible

Yeah, I mean, it's wild.It looks like an optical illusion.But yeah, we're going to explain it.This blade is the length of two of these handles.Here's the insertion points.And when they slide into each other, this knife's unlocking that knife and that knife's unlocking that knife.

A little mechanism in the handle.But when they are unsheathed, they are totally usable.They are locked out of their handle.Pretty honestly, pretty amazing design.Very low blade play on the knife, too.Very low wiggle.

There are internal magnets inside the handle holding it, holding it together.I'll put more information on this in the description.
